Product Description:
The AKM41E-ACMNEH-00 is a brushless synchronous servo motor built for closed-loop motion duties in industrial machinery. Part of the AKM Synchronous Servo Motors series, it interfaces with a digital drive to provide accurate velocity and position control on packaging lines, pick-and-place gantries, and indexing tables. The motor combines a permanent-magnet rotor with a stator designed for rapid magnetic field changes, allowing the controller to adjust current quickly as the mechanical load varies. This responsive electromagnetic design helps the connected axis follow acceleration, speed, and positioning commands during repetitive operating cycles. The compact housing reduces moving mass at the load and leaves more installation space around nearby machine components.
Kollmorgen specifies the motor with an 84 mm frame, which determines its mounting footprint for attachment to compatible gearheads or machine plates. The housing uses an IEC flange with accuracy grade N, helping maintain concentric alignment and low radial runout during operation. This flange arrangement supports direct face mounting where accurate shaft positioning is needed for couplings, pulleys, or gearbox inputs. A keyway shaft transmits torque through a keyed coupling, preventing rotational slippage during repeated starts, stops, and direction changes. The connector arrangement allows power and feedback cables to be routed without interfering with the output coupling. The housing and mounting surfaces provide a rigid mechanical interface that helps limit unwanted movement between the motor and the driven assembly.
The motor is supplied without a brake, so an external holding device or active servo torque is required when a stationary load must be secured. Its rotor length index 1 indicates the shortest magnetic stack available for this frame, reducing rotor inertia and supporting rapid acceleration. Lower inertia allows the drive to change shaft speed with less stored rotational energy, which is useful for axes that perform frequent reversals or short indexing moves. The coil set carries winding designation e, with electrical characteristics that allow a compatible drive to deliver the required current and reach the intended operating speed. Correct drive settings are necessary for stable current regulation, effective feedback control, and appropriate thermal protection. The brake-free configuration also reduces rotating mass, although vertical or gravity-loaded axes require a separate means of preventing movement after drive power is removed.
